Selective Magnification in 3D Rendering Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in interacting with and differentiating virtual and real-world objects in 3D rendering systems when they are far away, especially in scenarios where physical movement is impractical due to obstructions or disabilities, leading to a diminished immersive experience.
Innovation Solution
An electronic device provides selective magnification by displaying a Region of Interest (ROI) as a close-up view alongside the original view, allowing users to interact conveniently while preserving the sense of space and depth, using a combination of real-time and offline spatial mapping, and allowing user-defined positioning of the magnified view based on user input or intent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user physically moves towards the objects to obtain an enlarged view, then the user can see the objects more clearly, but the user experience is worsened due to obstructions, disabilities, or impractical movement requirements
Solution Approach 1:
The patent creates a virtual copy of the real-world scene with augmented virtual objects, allowing users to interact with magnified versions of objects without physically moving. The system renders a 3D environment where objects can be zoomed in while maintaining the original spatial context, eliminating the need for physical movement towards objects.
Solution Approach 2:
The patent transitions from 2D screen display to 3D spatial rendering, allowing users to navigate and zoom within a virtual three-dimensional space. Users can move their view along virtual paths and zoom into objects without physical movement, as the system provides virtual displacement and magnification in the third dimension.
2Adaptability or versatility
If the system displays all objects far away from the user, then the immersive 3D experience is maintained, but the user cannot easily view and differentiate objects
Solution Approach 1:
The patent segments the 3D scene into multiple viewable regions, allowing users to focus on specific objects or areas of interest while maintaining awareness of the overall environment. The system can render different parts of the scene at different levels of detail and distance, enabling both immersive experience and detailed object differentiation simultaneously.
Solution Approach 2:
The patent implements dynamic rendering where the system can adjust the display based on user interaction and attention. Objects can be dynamically magnified or brought closer when users interact with them, while maintaining the original immersive 3D environment. The system adapts the rendering in real-time to balance immersion and detail viewing.
3Ease of operation
If the system provides a magnified view of objects, then the user can interact precisely with objects, but the sense of space and depth may be lost
Solution Approach 1:
The patent implements a nested view structure where magnified views of objects are contained within the larger 3D scene context. Users can zoom into objects for precise interaction while the original spatial environment remains visible in the background, similar to nested dolls. This allows detailed viewing without completely losing the sense of space and depth.
Solution Approach 2:
The patent introduces virtual navigation paths and transition mechanisms as intermediaries between the user's view and the magnified objects. These virtual pathways guide the user's perspective through smooth transitions that preserve spatial continuity, allowing precise object interaction while maintaining the original 3D spatial perception through controlled view changes.

AI summary
A method for selective magnification in a 3D rendering system includes: displaying, by an electronic device, a first view including at least one real world object and at least one virtual object; displaying, by the electronic device, a second view comprising a region of interest (ROI) in the first view, while displaying the first view; receiving, by the electronic device, a user interaction on the second view; and generating, by the electronic device, interaction on the first view corresponding to the user interaction received on the second view.
